摘要:

AbstractAssorted procedures for solutions of geometric and gravimetric problems on a sphere are reviewed. These and similar procedures allow the use of a sphere as a simple model for the Earth.Specific topics elaborated are:Compartments—size and shape, area and centre of gravity.Distances—angular and spatial, total number of distinct distances.Attraction and potential—formulas for compartments and mass-lines, rigorous and approximate solutions for caps.

摘要:

AbstractUnlike Great Britain and Western Europe, most Commonwealth countries have legislation in the form of a Land Survey Act or Ordinance which not only controls the licensing, registration and duties of surveyors but also prescribes regulations controlling the method of executing surveys and the degrees of accuracy which must be attained. This legislation generally applies chiefly to cadastral surveys but does cover in many cases the conduct and control of trigonometrical, topographical and geodetic surveys.

摘要:

AbstractA brief review is given of the development of computing aids since Babylonian times with emphasis on the last 400 years leading up to the advent of electronic computers and calculators.Electronic desk calculators, both programmable and non-programmable, are proving extremely useful in all forms of computation, and details are given of the Hewlett–Packard machines of the former category, including their internal operation and particular suitability to survey problems.

摘要:

AbstractIn its atmosphere of informal efficiency, pleasant social intercourse, and a feeling of time well spent in the technical sessions, this Conference was as satisfactory as any in the series, apart from an undercurrent of complaint about the price of morning coffee and afternoon tea.

摘要:

AbstractThe problem was posed in our issue No. 148, and the solution published in No. 153 was provided by Mr. B. R. Bowring, who evidently did not cease to think about the problem, for he has now sent us the ideas embodied in the solutions given below.
